On the newly launched Represent.LA map, more than 300 technology-related companies have been plotted online, including 257 start-ups, 22 accelerators and incubators, and 34 investors. Click on the icons and a short description of each firm appears.

Viewers can submit the names of companies they think should be added to the map.

The map was created by three techies, including Alex Benzer, founder of SocialEngine, who said their hope is to connect and promote the local tech start-up community.
